[Lxc-users] Determine which veth interface belongs to which container

[Yury Vidineev]

Looks like it isn't correlate. On host:

cat /sys/class/net/veth*/iflink|sort -n
6
15
60
63
65
66
71
75
76
82
85
88
91

In containers:

for i in $(lxc-ls); do ssh $i cat /sys/class/net/eth0/iflink; done|sort -n
5
14
59
62
70
81
84
87
90
